CIRCULATING OIL-WH EEL Specification of Letters Patent.

Application filed March 7, 1905. Serial No. 248,944.

To all wia/07% it may concern,.-

Be it known that I, GEORGE T. WRIGHT, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Circulating Oil- Wheels, of which the following is a specification, containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in circulating oil-wheels; and it consists of the novel features herein shown, described, and claimed.

In the drawings, Figure 1 is an outside elevation of a circulating oil-wheel embodying the principles of my invention. Fig. 2 is a perspective sectional detail upon an enlarged scale.

Referring to the drawings in detail, my improved circulating oil-wheel is preferably cast all in one piece; but it is only essential that the hub be cast in one piece. The spokes and rim may be made separate. The hub com- I A prises the axle-box having the spindle-open-- ing 3 extending continuously from end to end of the hub, there being a solid ring 4 around the inner end of the spindle-opening, there being radial slots 5, 6, and 7 through the wall of the axle-box outside of the ring 4, there being oil-chambers 8, 9, and 10 communicating with the slots 5, 6, and 7, the walls 11 of said chambers farthest away from the center' being inclined from the periphery of the ring 4outwardly and toward the center, the outer end face 12 of the axle-box being iinished on a transverse line, there being annular pockets 13, 14, and 15 around the outer end, said pockets being separated by the walls 16, 17, and 18, there being a iange 19, forming the outer wall of the pockets 13, 14, and 15, and the axial face 20 of said iange being finished, said axial face 20 being outside of the transverse face 12. It is intended that the end face of the bearing shall lit against the transverse face 12 and the periphery of the bearing shall fit Within the axial face 20. Lubricating-oil is fed into the pockets 13, 14, and 15 and from said pockets runs inwardly along the inclined walls 11 when said walls are below the center of the axle," and said oil runs outwardly again along said walls 11 when the walls areabove the center of the axle.

I desire to call especial attention to the pockets having the inclined walls 11, as it is by the inclination of these walls that I keep up a constant circulation of oil to the bearingsurfaces.

I claim- In a circulating oil-wheel: a hub comprising an axle-box having the spindle-opening 3; there being a solid ring 4 around the inner end of the spindle-opening; there being radial slots 5, 6 and 7 through the wall of the axlebox outside of the ring 4; there being oilchambers 8, 9 and 10 communicating with the slots 5, 6 and 7; the walls 11 of said chambers farthest away from the center being inclined from the periphery of the ring 4 outwardly and toward the center; the outer end face 12 of the axle-box being iinished on a transverse line; there being annular pockets 13, 14 and 15 around the outer end of the axle-box; said pockets being separated by the walls 16, 17 and 18; there being a flange 19 forming the outer wall of the pockets 13, 14 and 15; and the axial face 20 of said flange being finished; said axial face 2O being outside of the transverse face 12.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

GEORGE T. WRIGHT.
